Description. Lengths. Ƌ: body, 3.0 mm; wing, 2.8 mm. Male. Head: globular, frons shining brown, yellow above antennae; face yellow; gena yellow, silvery pollinose, row of short black white ventrally; occiput brown, brown posteroventrally with white posterolateral spot; clypeus thin, yellowish brown; palpus ( Fig. 13 View FIGURES 10 – 17 ) with long thin, yellow stem-like base and black clubbed apex making it appear racquet-shaped, without apparent vestiture; proboscis brown.

Antenna ( Fig. 21 View FIGURES 18 – 25 ) yellow; flagellomere subovoid, clothed with white hairs, with long, slender, curved brown dorsal process, densely clothed with decumbent white hairs, four times length of flagellomere; arista one-half length of dorsal process, styliform, bare.

Thorax: shining; mesonotum and scutellum shining yellowish brown, minute brownish setulae in rows along slightly darker medial, paired dorsocentral and postalar stripes; pleura brown above, yellow below; anepisternum bare; katepisternum with white hairs ventrally near mid coxa.

Wing: hyaline; vein R2+3 nearly straight, ending in costa just beyond level of crossvein dm-cu; crossvein dm-cu almost perpendicular to CuA1; last section of CuA1 one-half length of dm-cu; crossvein r-m at middle of cell dm; veins R4+5 and M1+2 slightly converging distally; halter white.

Legs: yellow; fore coxa with 2 long yellowish white hairs; fore femur dorsally with 6 short black thorn-like spicules, ventrally with subbasal cluster of yellowish orange hairs appearing thorn-like; hind femur with minute knob-like protuberance basomesally; otherwise remainder of legs unmodified.

Abdomen: tergites I–II yellowish to tan, weakly sclerotized medially and laterally; tergites III–V brown laterally, yellowish brown medially, tergite VI brown, with short sparse brown hairs, these hairs longest laterally; sternites pale brown, weakly sclerotized medially.

Male genitalia. Not dissected; epandrium and surstylus shining brown, with white hairs; cerci white, narrow basally, flared and rounded apically, with long white hairs dorsally, shorter brown hairs apically and ventrally.

Female. Unknown.

Material examined. Holotype ♂ from the PHILIPPINES: [Negros Island]: Negros Oriental Province: Cuernos de Negros , 7 km west Valencia , 700 m, 21–31 May 1988, D.C. Darling, E. Mayordo, 873104, Malaise trap with pans ( CNC) . Holotype deposited in the Canadian National Insect Collection, Ottawa.

Distribution. Philippines.

Etymology. This species is named for tennis champion Roger Federer because of the distinctive racquetshaped male palpus.
